ST-510 Poly Trigger Gun 18.5 GPM 365 PSI

The ST-510 Poly Trigger Gun is a high-volume, low-pressure trigger gun purpose-built for softwash and chemical application systems. Rated at 18.5 GPM at 365 PSI, this gun is designed to move large volumes of chemical solution at low pressure — making it the ideal trigger gun for softwash rigs, downstream injection setups, and any application where flow rate matters more than pressure. The poly construction keeps it lightweight and resistant to the harsh chemicals commonly used in softwash operations, including sodium hypochlorite and surfactants.
